In automated metrics, we should also aim to capture one of the core aspects of a dance performance: its ability to “follow the beat” of the song.
Previous work [1]}, [2]} has proposed using a beat alignment metric that rewards kinematic beats (local minima of joint speed) that line up with music beats.
In Li et al. [1]}, the distance is computed per kinematic beat, and in Siyao et al. [2]} the distance is computed per music beat.
